Sanchez, 35, and Winter, 32, exchanged vows in San Juan before 250 guests, including Eva Longoria Parker.
The Puerto Rican-born Sanchez wore a princess-style dress with hand-embroidered pearls and diamonds by Venezuelan designer Angel Sanchez, while Winter wore a Calvin Klein suit.
Winter proposed to Sanchez last December while on vacation on the resort island of Vieques, east of mainland Puerto Rico. He popped the question with a 4.3-carat brilliant-cut engagement ring by Michael Barin.
Earlier this year, Sanchez revealed her secret to a drama-free union to InStyle magazine: "Always be your husband's best friend," she said. "Make him laugh and give him a little bit of freedom - you can't suffocate him."
In addition to her work on CBS's Without a Trace, Sanchez has been ranked among the world's sexiest women by Stuff and Maxim magazines.
Winter has appeared on Days of Our Lives and CSI: Crime Scene Investigation.
